A smart genre shocker, “After Party” stars Luis Hernandez (“Three Steps Above the Sky”) and Ursula Corbero (“Paranormal Experience 3D“). Screenplay, by Larraya and Fernando Sancristobal, turns on a teen TV idol and three girls who wake up after a wild party to find themselves trapped in the house. He receives cell phone vids of the real-time deaths of other party revelers. But things may not be quite how they seem.

While many Spanish genre films skew older, weighing in more as psychological thrillers, “After Party” has “thriller elements but also horror targets young teen audiences,” said Film Factory’s Vicente Canales, who will introduce a promo to buyers at the Cannes Film Festival, which starts May 16.
